I don't know what the thread pitch/size is, but you should be able to get new ones at your Mazda dealer.

Is it 10x1.25? I believe that is what's on the turbos. 14mm bolts, thread is like 10x1.25 if I remember correctly.

Wrong.
They are 10mm x 1.50.
Go to the BMW dealer and ask for theirs - it's only like $1/each.
The BMW ones are 15mm hex though.
